Question

(x+1)(x-1)(x-5)=0 решите пд

Answer 1

$(x + 1)(x - 1)(x - 5) = 0 \\ x + 1 = 0 \\ x = - 1 \\ x - 1 = 0 \\ x = 1 \\ x - 5 = 0$
х=5

Ответ: 5; 1; -1

Answer 2

X+1 =0 или х-1 =0 или х-5=0
Х1=-1 Х2=1. Х3=5

Answer 3

To solve the given polynomial equation $(x+1)(x-1)(x-5) = 0$, we can use the zero product property, which states that if the product of two or more factors is equal to zero, then at least one of the factors must be zero.

So, to find the solutions for $x$, we set each factor to zero and solve for $x$:

1. $x + 1 = 0$ Subtract 1 from both sides: $x = -1$

2. $x - 1 = 0$ Add 1 to both sides: $x = 1$

3. $x - 5 = 0$ Add 5 to both sides: $x = 5$

Therefore, the solutions to the equation $(x+1)(x-1)(x-5) = 0$ are $x = -1$, $x = 1$, and $x = 5$.
